Abstract

La présente invention a pour objet une mousse polymère extrudée préparée au moyen d'une composition de polymère thermoplastique d'un copolymère styrène - acrylonitrile ayant une teneur en comonomère acrylonitrile copolymérisé de 20 pour cent en poids ou moins, une teneur moyenne en comonomère acrylonitrile qui dépasse sa teneur médiane en comonomère acrylonitrile et une distribution moyenne du comonomère acrylonitrile copolymérisé ayant une largeur à mi-hauteur qui est supérieure à 2,5 pour cent en poids telle que mesurée à la mi-hauteur du pic d'une courbe de distribution du comonomère acrylonitrile copolymérisé pour le copolymère styrène - acrylonitrile.
